Category 2 Cable
Category 2 cable, also known as Cat 2, is a grade of unshielded twisted pair cabling designed for telephone and data communications. The maximum frequency suitable for transmission over Cat 2 cable is 4 MHz, and the maximum bandwidth is 4 Mbit/s. Cat 2 cable contains 4 pairs of wires, or 8 wires total. Official TIA/EIA-568 standards have only been established for cables of Category 3 ratings or above. Though not an official category standard established by TIA/EIA, Category 2 has become the de facto name given to Level 2 cables originally defined by Anixter International, the distributor. Anixter ''Level 2'' cable was frequently used on ARCnet and 4 Mbit/s Token Ring Token Ring network IBM hermaphroditic connector with locking clip. Screen contacts are prominently visible, gold-plated signal contacts less so. Token Ring is a computer networking technology used to build local area networks.

Tropical Cyclone Scales
Tropical cyclones are ranked on one of five tropical cyclone intensity scales, according to their maximum sustained winds and which tropical cyclone basins they are located in. Only a few scales of classifications are used officially by the meteorological agencies monitoring the tropical cyclones, but other scales also exist, such as accumulated cyclone energy, the Power Dissipation Index, the Integrated Kinetic Energy Index, and the Hurricane Severity Index. Tropical cyclones that develop in the Northern Hemisphere are unofficially classified by the warning centres on one of three intensity scales. Tropical cyclones or subtropical cyclones that exist within the North Atlantic Ocean or the North-eastern Pacific Ocean are classified as either tropical depressions or tropical storms. Should a system intensify further and become a hurricane, then it will be classified on the Saffir–Simpson hurricane wind scale, and is based on the estimated maximum sustained winds over a 1-minut ...

Northeast Snowfall Impact Scale
The Northeast Snowfall Impact Scale (NESIS) was created to measure snowstorms in the U.S. Northeast in much the same way the Saffir-Simpson Hurricane Scale records hurricane intensity and the Enhanced Fujita Scale with tornadoes. The Scale NESIS was created by Paul Kocin of The Weather Channel and Louis Uccellini of the National Weather Service, classifies storms in one of five ways that range from ''Notable'' (the weakest designation) to ''Significant'', ''Major'', ''Crippling'', and ''Extreme''. storms have on the economy and transportation throughout the major cities in the Northeastern United States as well as the country as a whole.http://www.ncdc.noaa.gov/snow-and-ice/nesis.phpref The variables measured on the scale include area, amount of snowfall, and the number of people living in the path of the storm. These numbers are calculated into a raw data number ranging from "1" for an insignificant fall to over "10" for a massive snowstorm. Based on these raw numbers, the ...

Regional Snowfall Index
The Regional Snowfall Index (RSI) is a scale used by NOAA to assess the societal impact of winter storms in the eastern two-thirds of the United States and classify them into one of six categories. The system was first implemented in 2014, and is a replacement for the Northeast Snowfall Impact Scale (NESIS) system which the National Climatic Data Center (NCDC) began using in 2005. The NCDC has retroactively assigned RSI values to almost 600 historical storms that have occurred since 1900. Storms are ranked from Category 0 "Nuisance" to Category 5 "Extreme" on the scale. The impact of the storms is assessed in six different regions of the United States: the Northeast, Northern Rockies and Plains, Ohio Valley, South, Southeast, and Upper Midwest. The index makes use of population and regional differences to assess the impact of snowfall. For example, areas which receive very little snowfall on average may be more adversely affected than other regions, and so the index will grant st ...

List Of Northeast Snowfall Impact Scale Winter Storms
The Northeast Snowfall Impact Scale (NESIS) is a scale used to categorize winter storms in the Northeast United States. The scale was developed by meteorologists Paul Kocin and Louis Uccellini, and ranks snowstorms from Category 1 ("notable") to Category 5 ("extreme"). Only two historical blizzards, the 1993 Storm of the Century and the North American blizzard of 1996 are rated in the 5 "extreme" category. The scale differs from the Saffir–Simpson Hurricane Scale and Fujita Scale, which are used to classify tropical cyclones and tornadoes, respectively, in that it takes into account the number of people affected by the storm. The scale, as devised, is intended chiefly to assess past storms rather than assist in forecasts.Kocin and Uccellini, pp. 269–270 List There are two available values for NESIS. The original values that Paul Kocin and Louis Uccellini computed for storms in their original 2004 work "A Snowfall Impact Scale Derived From Northeast Storm Snowfall Distr ...

Categories Of New Testament Manuscripts
New Testament manuscripts in Greek are categorized into five groups, according to a scheme introduced in 1981 by Kurt and Barbara Aland in ''The Text of the New Testament''. The categories are based on how each manuscript relates to the various text-types. Generally speaking, earlier Alexandrian manuscripts are category I, while later Byzantine manuscripts are category V. Aland's method involved considering 1000 passages where the Byzantine text differs from non-Byzantine text. The Alands did not select their 1000 readings from all of the NT books; for example, none were drawn from Matthew and Luke. Description of categories The Alands' categories do not simply correspond to the text-types; all they do is demonstrate the 'Byzantine-ness' of a particular text; that is, how much it is similar to the Byzantine text-type, from least (Category I) to most similar (Category V). Category V can be equated with the Byzantine text-type, but the other categories are not necessarily re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Measurement Category
Measurement category is a method of classification by the International Electrotechnical Commission (IEC)http://assets.fluke.com/Appnotes/2042049_w.pdf of live electric circuits used in measurement and testing of installations and equipment, usually in the relation within a building (residential or industrial). The categories take into account the total continuous energy available at the given point of circuit, and the occurrence of impulse voltages. The energy can be limited by circuit breakers or fuses, and the impulse voltages by the nominal level of voltage. Measurement categories Measuring circuits are subjected to working voltages and transient stresses from the circuit to which they are connected during measurement or test. When the measuring circuit is used to measure mains, the transient stresses can be estimated by the location within the installation at which the measurement is performed. When the measuring circuit is used to measure any other electrical signal, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN Protected Area Categories
IUCN protected area categories, or IUCN protected area management categories, are categories used to classify protected areas in a system developed by the International Union for Conservation of Nature (IUCN). The enlisting of such areas is part of a strategy being used toward the conservation of the world's natural environment and biodiversity. The IUCN has developed the protected area management categories system to define, record and classify the wide variety of specific aims and concerns when categorising protected areas and their objectives. This categorisation method is recognised on a global scale by national governments and international bodies such as the United Nations and the Convention on Biological Diversity. Categories Category Ia – strict nature reserve A strict nature reserve (IUCN Category Ia) is an area which is protected from all but light human use in order to protect its biodiversity and also possibly its geological/geomorphical features. These areas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Classification Of Non-silicate Minerals
This list gives an overview of the classification of non-silicate minerals and includes mostly International Mineralogical Association (IMA) recognized minerals and its groupings. This list complements the List of minerals recognized by the International Mineralogical Association series of articles and List of minerals. Rocks, ores, mineral mixtures, not IMA approved minerals, not named minerals are mostly excluded. Mostly major groups only, or groupings used by ''New Dana Classification'' and ''Mindat''. Classification of minerals Introduction The grouping of the New Dana Classification and of the mindat.org is similar only, and so this classification is an overview only. Consistency is missing too on the group name endings (group, subgroup, series) between New Dana Classification and mindat.org. Category, class and supergroup name endings are used as layout tools in the list as well. ;Abbreviations: * "*" – Mineral not IMA-approved. * "?" – IMA discredited mineral name ...
